Wolfserker

This is from last year actually, and I just recently remembered this and was planning on re-drawing this digitally but heck, now that I look at this it's pretty okay.

Anyway, when a wolf eats another wolf, it may get possessed by the wolf pelt that causes it to attack everything until it slowly dies from the infected wounds or gets killed.
And yes, if a human eats a wolfserker, he/she will get possessed by the double wolf pelt and same thing happens.
